 ## Specifications
 
-* 10 buttons
-* 8 potentiometers
+### Features
+* 10 buttons (9 general purpose + Page2)
+* 8 potentiometers (7 general purpose + Mode)
 * 2 expression pedals
 * USB MIDI class-compliant
 
+### How to use it
+Page2/Looper Btn
+* When activated (Led on) use second page for other buttons
+* No CC is sent when pressed
+Mode potentiometer (#8, the last one)
+* Left => Normal mode: Btn sends 127 when activated (Led On) and 0 on deactivation
+* Right => Bypass mode: Btn sends 0 when activated (Led On) and 127 on deactivation
+* Half => Disable potentiometers CC
+* No CC is sent when rotated
+Button CC values (excluded Looper/Page2 Btn)
+ {51, 52, 53, 54, 55, 56, 57, 58, 59}
+ {61, 62, 63, 64, 65, 66, 67, 68, 69}
+Potentiometers CC values (excluded Mode Pot)
+ {18, 19, 20, 21, 22, 23, 24};
+Expression pedal CC values
+ {16, 17};
